Dye Laser Model with Multiplicative Colored Noise

Abstract

A single mode laser model with fluctuating pump parameter is in use to describe the statistical properties of the light intensity of a Dye laser [1-4]. The normalized Langevin equation with multiplicative colored noise read where ϵ represents exponential correlated noise with the noise strength D and the relaxation time γ-4[5-7]. The equivalent two variable Fokker-Planck equation has the form [5,8,9]
